IMPROVEMENT IN RAILROAD-LAMPS.

Specification forming part of Letters Patent No. 36,274, dated August 26, 1862.

To all whom it may concern.-

Be it known that I, JOHN CARTON, of Utica, Oneida county, New York, have invented a new and useful improvement in the construction of railroad and similar lamps for the burning of coal-oil or kerosene, of which the following is a specification.

The nature of my invention consists in inserting in the space between the two tubes which compose the burner, below the wick and above the feed-tube, a perforated metallic ring, closing the space and compelling all the oil fed to the wick to pass through such perforations, by means of which the sudden jars of the locomotive no longer throw upon the wick an excess of oil and cause the lamp to smoke or the oil to run over upon the reflector; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, in which- Figure 1 is a sectional view of the burnertubes and ring in place. Fig. 2 is a perspective view of the ring, and Fig. 3 is a perspective View of the ring attached to the end of the wiclcthimble.

A is the ring.

A is the ring attached to the wick-thimble.

B is the outer tube, and B the inside tube of the burner.

- C is the wick-thimble.

D is the opening communicating by the feedtube with the oil-can, and D is the feed-tube.

E E is the bottom of the space between the two tubes B and B, closing it at the lower end. The tubes B and B are madein the usual mode and are closed at the bottom E E and below the feed-tube D. At a short distance above the feed-tubes-say from a quarter to a-half of an inch-is placed the perforated ring A, which is made of metal and adjusted to fit closely between the two tubes, and may be soldered to one. or both of said tubes, so that no oil can ever pass between the ring and the tubes. The ring is pierced with small holes, through which the oil passesto the wick.

Instead of attaching the ring A near the bottom of the tubes, it may be attached to the lower end of the wick-thimble, as seen in Figs. 1 and 3, and made to rise and fall with the wick, or the ring may be used in both places;

and instead of a metallic ring any porous substance, as sponge or the like, may beused, the purpose of said perforated ring or porous substance being to allow only a sufficiency of oil to pass to the lamp at all times, and at the same time toprevent any excess of oil being forced up into the wick by the jarring motion of the locomotive.

I claim- The perforated ring (one or more) or other equivalent material, in combination with the tubes B and B, constructed and operating substantially as described; 7
